A particle of mass m and charge q is accelerated along the +x axis (in the plane of the page) from rest through an electric potential difference V. The particle then enters a region, defined by x> 0, containing a uniform magnetic field. V = 400.0 V B = 0.850 T q = -1.602 × 10-' m = 6.68 × 10-27 B = 0 9. What is the radius of the particle's path, and how long does it take the particle to exit the magnetic field region?
